140th New York Volunteer Infantry Regiment

The 140th New York Volunteer Infantry Regiment was a volunteer infantry regiment of the US Army that was active from 13 September 1862 to 3 June 1865. The regiment was organized in Rochester, New York, and its 10 companies of 100 men each were primarily recruited from Rochester and the surrounding Monroe County. The regiment was led by Patrick O'Rorke, who graduated first from his class at West Point in June 1861. It fought at Fredericksburg, Chancellorsville, and then at the Battle of Gettysburg, where O'Rorke led his men to the rescue of Strong Vincent's brigade on Little Round Top. O'Rorke led the infantry regiment, which had not been carrying loaded weapons, in a bayonet charge against the Confederate troops, and he was shot in the throad and killed. Afterwards, it fought at Bristoe Station, Rappahannock Station, and Mine Run. In 1864, it fought at the Wilderness, Spotsylvania, and Cold Harbor during the Overland Campaign, and the party was present at the end of the war at Appomattox Court House in 1865. In June 1865, the regiment was disbanded at Alexandria, Virginia.
